IPAIDLOCK.

Specification of Letters Patent. Patented Sept. 11, 1915.

Application filed May 15, 1915. Serial No. 28,393.

To all whom it may concern Be it known that I, J onsrnn S. RoGnRs, a citizen of the United States, residing at Laurelhill, in the county of WValton and State of Florida, have invented a new and useful Padlock; and ll do hereby declarethe following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' This invention relates to the art of locks and latches, and particularly to a new and useful padlock of the'gear type.

An object of the invention is the provisionof a padlock casing having a segmental gear bolt journaled therein, there being double means in the casing for locking the segmental gear bolt against being unlocked. However, after the gear bolt is unlocked the same may be operated to an open position by gear connections with a suitable key.

a In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a view in side elevation of the improved padlock. Fig. 2 is an edge elevation. Fig. 3 is a sectional View on line of Fig. 2 showing parts in elevation, in other words showing the cover plate of a casing removed, and the riveted pins for securing thecover plate in place in section, and illustrating the segmental gear bolt locked in its closed position. Fig. 4: is a view similar to Fig. 3 showing the segmental gear bolt unlocked and thrown open. Fig. 5 is a sectional view on line 5-5 of Fig. 3. Fig. 6 is a sectional view transversely of Fig. 3 on line 66 thereof. Fig. 7 is a transverse sectional view on line 7-7 ofFig. 3. Fig. 8 is a detail perspective view of the segmental gear bolt, and the gears for operating the same, and illustrating the means for doubly locking the segmental gear bolt against being opened. Fig. 9 is a detail perspective view of an abutment which must be first operated to unlock the segmental bolt. Figs. 10 and 1 1 are detail views of two keys to be .used in conjunction with the lock for unlocking the same.

Referring to the drawings, 1 designates a pin 7.

rectangular casing, but which may be any other desirable or suitable shape. This cas: ing comprises a body2 and a cover plate 3, which is secured to the body by means of riveted pins or the like 1. The body 2 is chambered or hollowedout to, form a suit able pocket 5, the upper portion of which is semi-circular in' contour as shown at 6, and journaled upon a pin 7 of the casing is a segmental gear member 8 having the gear teeth 9 and'the semi-circular bolt 10.

In Fig. 3 the segmental gear member 8 is in a position so that the bolt 10 is locked,

and in Fig. 4c the segmental gear member has been operated, therefore the bolt 10 is unlocked. The pocket 5 is provided with a plurality of offset recesses 11, 12 and 13. Loosely mounted upon a pin 1% in the recess 11, by reason of an elongated slot 15 is the shank 16 (in which the slot 15 is formed) of the abutment dog 17 which is provided with an abutment shoulder .18, which, before the dog is thrown outwardlytoward the cover plate, lies in the path ofthe segmental gear member, therefore assisting in preventing the member from being actuated upon the Secured in a recess 19 by means of small screws 20 is a leaf spring 21, the free end of which is forked as shown at 22, to straddle the, pin 23, which passes through an elongated slot 24 of the dog, so that the dog may be moved toward the cover plate. The leaf spring 21 acts to hold the dog toward the segmental gear member, so that the shoulder 18 will be in the path of the edge portion 25 of the segmental gear member, to prevent it from being operated. The inner face of the dog beyond the shoulder 18 is provided with a curved cam cutaway portion 27, and extending outwardly from the portion 28 of the casing is a key pin journal 29 for the barrel 30 of the key 31. This key 31 isprovided with a cam tongue 32,

which, when the key 31 is turned, passes bebind the dog and cams against the cutaway portion 27, thereby moving the dob: toward the cover plate, against the action of the leaf spring 21, and moving the shoulder 18 from the path of theedge portion 25 of the the-segmental gear memberwill be actuated,

so as to open or close the bolt 10. Secured at 37 in the recess 12 (the bottom of which is not quite as deep as the bottom of the pocket fromfwhere the pins 23 and pro ject) is a bar 38 having a, slot 39, through which the pin 35 extends.

gear member 8,,ar'1d the free end of the bar 38is provided with a laterally extending lug 40, whichengages a recess 41011 theinner face of the segmental gear member, thereby additionally locking the segmental gear member against being actuated; A spring 43, which is secured at 44 in the recess 13, acts to'press the bar 38 and the gear 36 out- Wardly toward'the cover-plate, so as to hold the lugs 40 in the recess 41 of the segmental gear member. The free end of the leaf spring 43' has an elongated slot 45, through which the pinf extends. The outer face of the gear 36 is provided with a slight recess' '46,'which partially surrounds the pin 35, to receive thebarrel 47,0f the key 48,

whereasthe projecting wings 49 of the key barrel enter the lateral recesses 50 of the gear 36,and when the key 48 is so arranged to engage: the gear, and subsequently to 1 pressing against the gear to'disengage the lug from the recess 4l against the action ofthe spring 43, theigear 36 maybe rotated,

which inturn will rotate the gear 34 and the'segmental gear 8, that is, after the shoulder18 has been moved from the path of the edge 25 of the segmental gear member. YVhen thesegmental gear member-is rotated in the direction of the arrow a, the bolt 10 s thrown open, and while being thrown open,the face (which is adjacent the cover pl te) of the segmental gear member will ride upon the enlarged portion of the dog, and the lug 40 willride upon the opposite face' of the gear member 8; When the segmental gear member isthrown in a reverse direction the bolt 10 is moved to a closed positiominwhich case the shoulder 18 and the lug'40 respectively of the dog and the bar 38 will spring'into locked engagement with the segmental gear member automatically 7 7 7 The invention having been set forth, what 7 is claimed as new and useful is 11A padlock comprising a casing, a seg-- mental gear memberhav ng a semi-circular bolt mountedlnthe casing for partial revoluble movement, a spring retained dog, having an abutment shoulder lying in the path of the segmental gear member to lock the same against movement, and gear connections "adapted to be actuated by a member for partially rotating the segmental gear 7 V V, This bar 38 ex tends behind the. gear 36 and the segmental member when the shoulder is its path to unlock the bolt.

2. A padlock comprising a casing, a seg mental gear member having a semi-circular bolt mounted in the casing for partial revoluble movement, a spring retained dog having an abutment shoulder lying in the path of the segmental gear member to lock the same against movement, and gear connections adapted to be actuated by a member for partially rotating the segmental gear member when the shoulder is thrown from its. path to unlock the bolt, a spring rctained bar mounted in the casing and underlying one of the gears of said connections and provided with a lateral lug at its free end, said segmental ear member having a recess to receive said ug to additionally lock the segmental gear member, said connections when actuated by the member adapted to be pressed by said member toward the back of the casing, and constituting means to withdraw the lug from the recess. a
